Description

Dust removal structure for ball mill

Technical Field

The application relates to the field of ball mills, in particular to a dust removal structure for a ball mill.

Background

The fly ash is the main solid waste discharged by coal-fired power plants, and the combustion process of the fly ash in the power plants is that the coal powder is combusted in a suspension state in a hearth, most of combustible substances in the coal can be burnt out in a furnace, and incombustible substances (mainly ash) in the coal powder are mixed in high-temperature flue gas in large scale. The incombustible matter is partially melted by the high temperature and forms large, small and spherical particles due to the surface tension. The power plant fly ash is added into the concrete, so that a large amount of cement and fine aggregate are saved, and the water consumption is reduced. Before the fly ash is used as a cement production raw material, further pulverization is needed. Fly ash is often ground using a ball mill.
